C-01

Connectors: C-01, C-04, C-33

FUNCTION
If a failure is present in the wiring harness between
the joint connector (CAN2) and the joint connector
(CAN3), this diagnosis result will be set.

TROUBLE JUDGEMENT CONDITIONS
If a communication flag is not set for some of the ECUs
on the CAN-C line, the ETACS-ECU determines that
there is a failure.

TROUBLESHOOTING HINTS

｠

Malfunction of the connector [joint connector
(CAN2), joint connector (CAN3) or intermediate
connector failed]

｠

Malfunction of the wiring harness [open circuit
between joint connector (CAN2) and joint connector
(CAN3)]

DIAGNOSIS

Required Special Tools:

｠

MB991223: Harness Set

｠

MB992006: Extra Fine Probe

STEP 1. Check joint connector (CAN2) C-04, joint connector
(CAN3) C-01 and intermediate connector C-33 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.

The strand end of the twisted wire should be within 10 cm
(4 inches) from the connector. For details refer to P.54D-8.

Q:Are joint connector (CAN2) C-04, joint connector (CAN3)

C-01 and intermediate connector C-33 in good condition?

YES:

Go to Step 2.

NO:

Repair the damaged parts.

STEP 2. Check the wiring harness between joint connector
(CAN2) C-04 and joint connector (CAN3) C-01.

Strictly observe the specified wiring harness repair
procedure. For details refer to P.54D-8.

(1)

Disconnect joint connector (CAN2) C-04 and joint connector
(CAN3) C-01, and check the wiring harness.

(2)

Check the wiring harness between joint connector (CAN2)
C-04 (terminal No.6) and joint connector (CAN3) C-01
(terminal No.5)

DIAGNOSIS

(3)

Check the wiring harness between joint connector (CAN2)
C-04 (terminal No.19) and joint connector (CAN3) C-01
(terminal No.16)

Q:Is the wiring harness between joint connector (CAN2)

C-04 and joint connector (CAN3) C-01 in good condition?

YES:

The trouble can be an intermittent malfunction

(Refer to GROUP 00, How to use Troubleshooting/inspection
Service Points - How to Cope with Intermittent
Malfunction P.00-15).

NO:

Repair the wiring harness between joint connector

(CAN2) C-04 and joint connector (CAN3) C-01.

DIAGNOSTIC ITEM 14: Diagnose when the scan tool cannot receive the data sent by
combination meter.

When servicing a CAN bus line, ground yourself
by touching a metal object such as an unpainted

water pipe. If you fail to do so, a component
connected to the CAN bus line may be damaged.
